HOLD'ING SOCKET FOR BOBBINQ.

SPECIFICATION formingpart Of Letters Patent N0. 680,019, dated. August 6, 1901;

Application filed June 5; 1901. $eria1 No. 63,321. (No model.)

To all whom it may concern:

Be it known that I, J AMES BROWN, a citizen of the United States, residing at Pawtucket, in the State of Rhode Island, have invented a new and useful Improvement in Holding-Sockets for Bobbins, of which the following is a specification.

This nature of my invention consists in the combination of a tapering socket with clutch projections adapted for engagement with the notched end of a bobbin, as hereinafter set forth.

In the accompanying drawings, Figure 1 represents the side view of my improved bobbin-holding socket and the contained bobbin. Fig. 2 represents a partial section of the same, taken in the line 2 2 of Fig.1. Fig. 3 represents a side view of the whirl and bobbin-holding socket without the bobbin. Fig.- 4 represents a top view of the holding'socket separate from the whirl. Fig. 5 represents a section taken in the line 5 5 of Fig. 4:. Fig. 6 represents a side View of the notched end of the bobbin. Fig. 7 represents an end view of the same.

In the drawings, A represents the spindle; B, the whirl; O,the bobbin,and D the bobbinholding socket secured to the whirl, the said socket being preferably formed of sheet metal and having the inwardlytapered socket-chamber a and the inwardly-turned lips or clutch projections b 1), adapted for engagement with the notches c c at the lower end of the bobbin 0, the said bobbin being provided .with the outwardly-tapered surface d, which fits the inwardly-tapered surface 6 of the socket D. The bobbin 0 will therefore be held for rotation with the whirl by the engagement of the clutch projections 19 b with the notchesc c of the bobbin in connec tion with the engagement of the tapered surfaces 61 and e, which serve to hold the bobbin in proper position.

I claim as my invention- 1. The bobbin-holding socket, having the inwardly-turned lips or clutch projections adapted for engagement with the notches of a bobbin. i

2. A bobbin-holding socket, provided with an inwardly-tapered chamber adapted to fit the outwardly-tapered end of a bobbin, and with clutch projections, adapted for engagement with notches at the end of the bobbin.

JAMES BROWN.
